Abstract
Two branch-line (BL) couplers based an finite-ground coplanar-waveguide (FG CPW) structures are proposed. The first one uses the bended structure to re duce the size of the normal quarter-wavelength two-arm BL coupler. The seco nd one improves the bandwidth by adding external compensated networks, whic h are also folded for size reduction. In this study, the performances of th ese BL couplers are examined, theoretically and experimentally.
